Radon is a naturally occurring radioactive gas formed in the ground. It is tasteless, odourless and colourless. Radon can move through the soil and into the atmosphere, seeping into homes and workspaces through cracks in the foundation, walls and floors.
More than 100,000 homes and businesses across the country are exposed to dangerously high levels of Radon gas. Radon levels are measured in becquerels per cubic meter of air (Bq/m3). The recommended action levels for long-term Radon exposure in homes is 200Bq/m3, above which remedial measure should be considered. It’s essential to note that this reference level is not a hard and fast boundary between safe and dangerous levels, but rather a guideline indicating when it’s time to take action to reduce Radon concentrations.
